Hey guys im gettin the hooker long tube headers and i know i can use the mufflex y pipe but is there anyway to get it in just 3inch pipe and not the 3in to 4in? also would i have to do any cuttin to my crossmember or anything for fittin it in? becuz im ordering my headers next week and want to know if the y pipe could be just 3in all the way instead of the 3in to 4in.
